Gran Bretaña: The scourge of late blightin potato crops
Potato late blight, caused by the oomycete pathogen Phytophthora infestans, continues to be the most economically destructive disease of global potato crops, writes Richard Halleron.
The disease is responsible for £1,000,000,000 of annual losses in the EU alone.
Across the island of Ireland it is estimated that £5.5 million is spent annually on fungicides to mitigate the impacts of the disease, which represents between 15-20 fungicide applications per season.
Given our climatic conditions during the summer months where such preventative measures are not applied losses of up to 100% can be experienced.
